Sound, Character and Stereo Control

Resonance-style broad EQ curves make it easy to add polish to a single track or to shape a bus or full mix. Resonance-style broad EQ curves are paired with expanded mid bands for flexibility.

A Tube Warmth control adds saturation and density when a sound needs more character. Stereo and Mid/Side modes let you shape the center and sides of a mix separately, which suits buses and stereo-aware tone control.

Workflow on MPC, Force and Desktop Hosts

The plugin is available for MPC Standalone and desktop plugin workflows. On MPC and Force hardware it is designed for systems running firmware 3.9.1 or newer, and it supports models including MPC One, MPC Live, MPC X, MPC Key and FORCE.

Band bypass toggles, output volume and a bypass control keep the interface quick to adjust while you work.
